I have a smiple set of values:
a<-c(1,2,3,1,5)
b<-c(2,2,2,2,2)
c<-c(2,3,4,2,6)
Then I use data.frame(table(paste(a,b,c)))to determine the frequancy of each set of values occures and get the result:
Var1 Freq
1 1 2 2 2
2 2 2 3 1
3 3 2 4 1
4 5 2 6 1
This is exactly what I need although the paste function puts the values into a string. I want to split the var1 into three variables while hanging onto the frequancy count so the result would be like:
v1 v2 v3 Freq
1 1 2 2 2
2 2 2 3 1
3 3 2 4 1
4 5 2 6 1
What is the best way to do this?
Thanks in advance,
Philip.
